RECOZL-LOADING PISTOL;

Application filed June 16,

To all whom it may concern:

Be it known that I, Josnr NicnL, a citizen of the German Republic,residing at No. 8 of Hauptstrasse, in'the city ofOberndorf-on-the-Neckar, Germany, have invented certain new and usefulImprovements in Recoil-Loading Pistols, (for which I have filedapplications in Germany Apr. 20, 1916; France Mar. 80, 1921; BelgiumMar. 31, 1921; Spain Mar. 30, 1921; Sweden Mar. 29, 1921; Italy Mar. 29,1921; Poland Jan. 17, 1920; Rumania Feb. 20, 1920; Austria Apr. 16, 1917Turkey Sept. 10, 1918; Hungary May 2, 1917; CZecho-Slovakia Dec. 22,1919,) of which the following is a specification.

This invention relates to a hammer-actuated recoil-loading pistol,having a breechslide provided with grooves and adapted to slide andreciprocate on guiding ribs of the grip-stock after firing.

The object of the invention is to provide a weapon with means forpreventing, in case of fracture of the breech-slide, the broken off rearportion of the said breech-slide from flying out and hurting theshooting person.

To this end one or both guiding ribs of the grip-stock and thecorresponding groove or grooves of the breech-slide are stepped,recessed or shaped, as regards their dimensions, in a manner, that incase of fracture the broken off rear-portion of the breechslide iscaught and retained within the pistol.

Referring to the accompanying drawings, which illustrate one embodimentof the invention, to the details of construction of which the inventionis not limited, however, the less so since only one groove and rib isshown to he stepped, while both grooves and ribs may be stepped, withoutthereby departing from the gist of the invention. 7

Fi ure 1 is a side view of the pistol with the handle broken off,

Figure 2 is a horizontal. longitudinal section on the line 22 of Figure1,

Figure 3 is a front view of the grip-stock and Figure 4 is a view of thebreech-slide seen from below.

The grip-stock a has two lateral guiding ribs 7) and 0 adapted to co-actwith corre sponding grooves e and 7 in the breech-slide d in order toguide the latter in its reciprocal movements, as usually in pistols ofthis type. In the shown embodiment of the in Specification of LettersPatent.

vention the front part of the guiding rib b denoted by the arrow-line m,Figure 1, is of less width than the rear part of the rib marked by theletter y, so that a step or shoulder g is formed serving as an abutmentor stop for the breech-slide, provided to receive and co act with therib Z) of the grip-stock, and said slide is cut out or shaped in itsfront part back to the point it to just have a sufiicient width tosnugly embrace or enclose the rib Z), so that the breech-slide will beguided in its reciprocatory movements without any undue play. From saidpoint it backwards the groove 6 is of increased width in conformity withthe larger part :1 of the guiding rib b so that the breech-slide uponfiring does not encounter any impediment in its backward travel. Thisbackward movement of the breech-slide is limited by the returning springconnected with the front end thereof as is generally known in pistols ofthis kind.

In case of an accidental fracture of the breech-slide at firing thebroken off rear part of the slide is released from the action of thereturning spring and runs freely backwards, until the point it of theguiding groove 6 meets the step 9 of the guiding rib, whereby the run ofthe said broken off part is stopped and the part is prevented fromflying out. The step it is provided at a point where the cross-sectionalarea of the breech-slide is such as to avert fracture.

It goes without saying that as already stated, the other guiding grooveand the rib 0 may be stepped'in a similar manner, and the result aimedat by the invention may likewise be realized by reeessing or steppingthe ribs and grooves in a direction rectangular to that shown in theillustrated embodiment of the invention without thereby de parting fromthe gist of my invention.

i hat I claim to secure by the Letters Patent is:

1. In a recoil-loading pistol, the combination of a barrel, a gripstock,a bieeclrslicle guided'thereon, a guiding rib on said gripstock having astepped portion, and a guiding groove in said breech-slide having acorrespondingly shaped portion or step to engage with the said step ofthe guiding rib in case of accidental fracture of the breech-slide atfiring.

2. In a recoil-loading pistol, the combination of a barrel, grip-stock,a breech-slide thereon, two guiding ribs on said grip-stock having eacha stepped portion, and two guiding grooves in said breech-slide havingeach a correspondingly shaped portion or step.

3. In a recoil-loading-pistol, the combination of a barrel, agrip-stock, a'breech-slide thereon, a guiding rib on said grip-stockhaving a portion recessed in regard to its depth to form a step, and aguiding groove in said breech-slide correspondingly shaped.

4. In a recoil-loading pistol, the combination of a barrel, agrip-stock, a breech-slide thereon, two guiding ribs on said grip-stockhaving each a portion recessed in regard to their depth to form steps,and two guiding grooves in said breech-slide shaped correspondingly.

5. In a recoll-loading pistol, the combina- 'tion of a barrel, a gripst0cl a breech-slide
